if x is a x real number what is the sum of x and the opposite of x

a-1

b-0

c:-x

d- x+1/x

If the opposite of x is -x, then their sum is 0, however, if the opposite of x is 1/x, then their sum is (x+1)/x

the opposite of x is -x

x + (-x) = 0

1/x is the reciprocal of x

To find the sum of a number and its opposite, you can simply add them together.

In this case, let's consider the number as 'x'. The opposite of 'x' is '-x'.

So, the sum of 'x' and the opposite of 'x' is: x + (-x).

Now, let's simplify this expression:

x + (-x) = 0

Therefore, the correct answer is b) 0.
